Abstract
In the coordination of a data conversion server and a storage server which belong to different security domains, a client terminal is able to replace an authorization token for accessing the data conversion server with a temporary URL on the storage server, the client terminal, which is located outside the data exchange server, will be able to issue a temporary URL without authorization, resulting in a file operation which is not intended by the data conversion server being performed. Scopes for allowing a client terminal to access the data conversion server and scopes necessary for the issuance of a temporary URL are separated from each other, and a limitation is imposed so that the scopes for the issuance of a temporary URL can be used only by the data conversion server, thereby enabling secure provision of a temporary URL to an external client terminal.
